Calculator Energy Consumption of Electric Cars

Compare driven distance and consumed energy for different values and specifications. From one value, the others can be calculated. Most common in Europe is the specification kilowatt-hours per 100 kilometers (kWh/100km).
Energy per distance can be converted in distance per energy and vice versa. If one value is entered there and one value is entered in one of the two bottom lines, the other value of that line will be calculated. You can also enter two values in one of the two bottom lines, to calculate energy per distance and distance per energy. The units can be chosen at will.

Energy per distance: /

Distance per energy: /

Energy per :

Distance per :

Wh = watt-hour, kWh = kilowatt-hour
km = kilometer, mi = mile

All entered and calculated values represent the same volume. Which information makes more sense or is more useful depends on the application or the message you want to make with it. For example, if you want to know how far you can go, then the relevant value is in the fourth line, distance per kilowatt hours remaining in the battery.


With my Volkswagen ID.3, I have an average annual consumption of 17.1 kilowatt hours per 100 kilometers. In other words, with one kilowatt hour I can travel an average of 5.85 kilometers. For 300 kilometers, the expected consumption would be 51.3 kilowatt hours. And with 5 kilowatt hours I can probably travel 29.24 kilometers.

The Sion should have had a range of 250 km with a 35 kWh battery according to the WLTP guideline. This would have equated to a consumption of 14 kWh/100 km. It would have covered a distance of 7.14 km per kWh, or just over 107 km with 15 kWh. It's a pity that this great car was discontinued in early 2023 due to lack of funds!

In many cars, the battery level is not given in kilowatt hours, but as a percentage. For example, with a battery with 62 kWh, 40 percent battery means 62 kWh * 0.4, i.e. 24.8 kilowatt hours remaining.
